Viet Bars. Not to be confused with Viet Cafes.
Viet Cafes: Bikini waitresses that serve food and coffee. You watch sports, play scratchers or lotto tickets. Sometimes they have illegal video gambling machines.
Viet Bars/Restaurants: Cute waitresses (club attire) that serve beer, alcohol, and viet bar food. Typically you'll have to buy at least one +$200 bottle service (Hennessy Priviledge or Don Julio 1942). Cute (mostly Viet) waitresses in their 20s that will sit, drink, talk and hangout w/ you. Older Viet bars will have karaoke. Newer Viet bars will have a DJ playing EDM. Thurs - Sat they'll have strippers parading around the restaurant soliciting for $20 lap dances.
Mostly Viet dudes/gangsters doing blow in the bathroom.
UTR Viet Bars - You'll need a Viet friend to vouch for you if you're non Asian.
