Ichiban operates as a fast-casual sushi counter and poke bowl shop in Oklahoma City, positioned between quick lunch service and customizable protein bowls rather than full-service omakase or kaiseki dining. The model emphasizes speed and personalization over elaborate plating, making it a weekday lunch standby and casual dinner option.
The restaurant centers on two formats: premade nigiri and rolls served from a display case, and build-your-own poke bowls where diners select base (white rice, brown rice, sushi rice, or lettuce), raw or cooked protein, and toppings. Rolls include California, spicy tuna, Philadelphia, and seasonal specials; poke proteins range from ahi tuna and salmon to cooked options like shrimp and teriyaki chicken. The counter layout means no table service, and orders move quickly through the line.
Premade rolls cost between $6 and $9 each; specialty rolls at the higher end. Poke bowls start around $12 for a single protein and climb to $15 to $16 for premium proteins like fatty tuna or scallop. Add-ons such as extra toppings or larger portions run $1 to $3. For comparison, Sushi Neko, another Oklahoma City counter option, prices rolls similarly but charges slightly higher for poke bowls (starting near $13 to $14). Ichiban's portions are adequate for lunch but not oversized; a single bowl plus a roll is a standard meal for one person.
Ichiban differs from Tamashii Ramen + Izakaya, which focuses on ramen and cooked small plates in a sit-down setting with full bar service and higher overall cost (entrees $14 to $18). It also differs from sushi-focused full-service restaurants like Oka Sushi, where diners sit at tables or a bar and order from a server, with significantly higher price points for omakase or multi-course meals. Ichiban fills the fast-casual lane: choose Ichiban for a 15-minute lunch, choose Oka Sushi for a leisurely seated dinner, choose Tamashii for ramen and shared plates. Sushi Neko occupies nearly identical market space, so the choice between them depends on location convenience and which specific roll flavors suit you.
Ichiban works well for office workers seeking a protein-heavy lunch, those with limited time, and poke bowl customizers who want control over every element. It does not suit diners seeking an experience, a full bar, or hot cooked entrées beyond basic teriyaki or tempura. Vegetarians can build bowls with cucumber, avocado, and cooked tofu, though the menu leans protein-forward.
You enter, view the roll display and signage for poke bowl options, decide whether to order a roll, bowl, or both, and step through the line. Staff ask your base, protein, and toppings if building a bowl; rolls are grabbed from the case. Checkout happens at the counter. No seating is guaranteed; most customers eat in car or take the box back to an office. The transaction typically takes five minutes or less from entry to exit.
Verify current hours before visiting, as fast-casual spots often shift lunch and dinner windows seasonally. Parking depends on the specific Oklahoma City location; confirm whether the site occupies a standalone building or shares a parking lot. Payment method (cash, card, mobile) is worth confirming as well, particularly if you prefer one method.
Ichiban serves its purpose efficiently: affordable, fast, customizable Japanese protein in a stripped-down setting. It does not aspire to fine dining and does not need to; it reliably delivers lunch to people in a hurry.
