Planning a gathering for 10, 20, 30 or 50 guests and not sure how much Japanese food to order? Small group catering Singapore is exactly where Sushijiro shines. From our central kitchen, our Japanese culinary team builds menus that scale cleanly with your headcount, so a boardroom lunch for ten arrives as neatly as a 50-pax open house. Whether you need individually packed bento, a compact mini buffet, or a full spread with live-style sushi platters, the right format depends almost entirely on how many people you are feeding. This guide walks you through choosing by group size, with recommended formats, rough per-pax planning, minimum orders, delivery and our strict No Pork No Lard kitchen.
How to choose a Japanese catering format by group size
For small group catering Singapore events, three formats cover almost every scenario, and each suits a different headcount band:
- Bento sets — best for 8–20 pax, seated meetings, staggered eating, or anyone who wants tidy, individually portioned meals with no shared serving.
- Mini buffet — best for roughly 15–30 pax who want variety and a “spread” feel without committing to a large full-buffet minimum.
- Full buffet — best for 30, 50 and beyond, where abundance, choice and a generous table presentation matter.
Beyond headcount, consider whether guests are desk-bound or mingling and how long the food must hold. Seated, time-boxed events lean bento; social, free-flow events lean buffet. Share your pax count and venue and we will recommend a format.
Catering for 10 pax: bento or mini portions
For catering for 10 pax, individually packed Japanese bento is almost always the cleanest choice. Ten guests rarely justify the equipment and minimums of a full buffet, and bento removes the awkwardness of a small crowd hovering around a half-empty buffet line. Each guest receives a complete, balanced box — typically a protein (teriyaki chicken, salmon, or beef), rice or sushi, a side, and pickles — which is ideal for meetings, training sessions or intimate celebrations.
Plan on roughly one bento per person, with one or two spares if appetites run large. If your group prefers shared dining, a Japanese mini buffet is the next step up, though ten is usually at the lower edge of mini-buffet value. For tidy, fuss-free service at this size, explore our bento catering options.
Catering for 20 pax: mini buffet or premium bento
Twenty guests is the sweet spot where you have a genuine choice. Buffet catering for 20 pax works beautifully as a mini buffet: enough people to create a lively spread, but compact enough that a single table of dishes feels generous rather than sparse. Expect a curated selection — sushi or maki, a couple of hot mains, a noodle or rice dish, salad and dessert — set out for self-service.
If your event is seated or staggered (think a long meeting or a venue with limited table space), premium bento for 20 keeps things orderly while still feeling special. For mini-buffet planning at this size, budget around 6–8 distinct items so every guest finds something they enjoy, and confirm portions generously since 20 pax is small enough that a single popular dish can disappear quickly. This headcount is exactly what our mini buffet menus are designed around.
Catering for 30 pax: mini buffet stepping up to full buffet
At catering for 30 pax, you are at the crossover point between mini and full buffet. Thirty guests can still be served comfortably by a generous mini buffet, but it is also the threshold where a full buffet starts to make sense — more dish variety, larger trays, and a more abundant presentation that suits open houses, department lunches and family events.
Our guidance: if your guests will mingle and graze over an hour or more, step up to a full Japanese buffet for the extra variety and replenishment. If it is a tighter, time-boxed sitting, a robust mini buffet is more cost-effective. For 30 pax, plan around 8–10 items and account for repeat servings — a good rule is to over-cater the crowd favourites (sushi, karaage, gyoza) rather than spreading portions thin across too many minor dishes.
Catering for 50 pax and above: full buffet territory
For catering for 50 pax, a full Japanese buffet is the natural fit. At this scale you want breadth — multiple sushi and maki selections, several hot mains, noodles, rice, salads, sides and dessert — laid out so a large crowd can serve themselves without bottlenecks. A full buffet also lets us bring the visual generosity that anchors a 50-pax event, from sashimi-style platters to bountiful trays that hold well throughout service.
Planning for 50+ is less about per-person boxes and more about flow: enough serving stations, enough volume per dish, and replenishment timed to the crowd. We scale quantities so that no single item runs out early, and we plan for a comfortable margin above your exact headcount. For anything beyond 50, our team will tailor station counts, menu depth and replenishment to your venue and run-of-show.
Minimum orders for small group and mini catering Singapore
Most caterers set minimums by format, and Sushijiro is no different. Bento typically carries a per-order minimum quantity, which makes catering for 10 pax straightforward — ten boxes comfortably clears it. Mini catering Singapore and mini buffets usually require a minimum pax count (commonly in the 15–20 range), which is why 20 and 30 pax events fit them so well. Full buffets carry a higher minimum that suits 30 pax and above.
If your group sits just below a format’s minimum, you have two easy options: add a few spare portions to qualify, or switch to the format below it. Share your exact headcount when you enquire and we will tell you immediately which formats are available and what the minimums are.
How much food per pax to order
Getting quantity right is the difference between a memorable event and either waste or shortfall. As a starting point for Japanese catering:
- Bento: one complete box per guest, plus 1–2 spares for groups of 10–20.
- Mini buffet: roughly 6–8 items for 20–30 pax, portioned so each guest can take a satisfying serving with seconds of the favourites.
- Full buffet: 8–12 items for 30–50+ pax, with crowd-pleasers volume-weighted higher.
- Appetite factor: bump quantities up for dinner, longer events, or younger/larger crowds; trim slightly for light lunches.

Delivery islandwide
Sushijiro delivers islandwide across Singapore — CBD, industrial parks, condo function rooms or heartland homes — fresh and on schedule. We coordinate timing around your event start, advise on the best buffet setup window, and pack bento for clean, stackable handover. Tell us your address and timing when you request a quote and we will confirm logistics.
Dietary needs: strictly No Pork No Lard
Our entire kitchen operates strictly No Pork No Lard (NPNL), which makes Sushijiro an easy choice for mixed groups and inclusive workplace events. Please note we are NPNL but not halal-certified, so we never represent our food as halal. Beyond pork, we are glad to accommodate common requests — vegetarian portions, no-raw selections for the cautious, and shellfish considerations — when you flag them in advance. Let us know your group’s requirements and we will build the menu around them.
Frequently asked questions
What is the smallest group you cater for? Small group catering Singapore starts comfortably at 10 pax with bento. Below that, we can advise on the most practical option for your numbers.
Is buffet catering for 20 pax better as a mini buffet or bento? Both work. Choose a mini buffet for a social, self-serve spread, or premium bento for seated, staggered or space-limited events.
When should I switch from mini buffet to full buffet? Around 30 pax. If guests mingle and graze, step up to a full buffet for more variety; for tighter sittings, a mini buffet is more economical.
How far in advance should I order? Earlier is better, especially for catering for 50 pax and peak dates. A few days’ notice lets us secure your slot, menu and delivery window — though we will always try to help with shorter timelines.
Is your food halal? No. Our kitchen is strictly No Pork No Lard, but we are not halal-certified and do not claim to be.
