The Sansglu take
The place
Butterfly Belly sits on the North Park Blocks at 323 NW Park Ave, a sibling-run Vietnamese and pan-Asian spot open since 2013. Founder Minh Tran left a 14-year engineering career at Intel to run it, and the restaurant helps fund the family's youth-education nonprofit.
The gluten-free setup
The kitchen is dedicated gluten-free with its own fryer, and current community listings report dedicated prep space, glove changes, and knowledgeable staff. The bar pours regular tap beers, so keep drinks in mind; everything from the kitchen itself is gluten-free.
What to order
The menu lists the 48-hour bone broth beef pho as the house signature, alongside pad thai, yellow curry, fried rice, and egg rolls from the dedicated fryer.
The move
It closes Sundays, and weekday service starts late afternoon, so treat it as a dinner spot. Order the pho on your first visit; the 48-hour broth is the reason to come.
