The Sansglu take

The place

Fully gluten-free Japanese spot built around onigiri, the stuffed rice balls that become your entry point to a whole menu you don't usually get to eat. Counter and bar seating, minimal but focused.

The gluten-free setup

Runs gluten-free end to end. Dedicated fryer for fried items, dedicated kitchen, gluten-free ingredients across the board. No wheat flour on the premises.

What to order

The onigiri itself, in whatever filling calls to you (fish, pickle, seasoning combinations that don't exist in most American Japanese spots). If they run fried items, those land clean here. Ask what's seasonal or what moves fastest through the kitchen to eat at peak freshness.

The move

Go when you want to spend time at the counter without pressure. Ask staff what they're excited about that day, since a gluten-free-only operation means the whole menu is actually yours.
