Is pricey, but is an all you can eat sushi buffet with good decent food that's sure to make you full.
Cajun Deli: 8038 Brooklyn Blvd, Brooklyn Park, MN 55445
Some great Cajun seafood, but I'm a big fan of their po boy meals which are only $10 - $12, and that is a reasonable price for fresh, straight bussing food, especially nowadays with inflation.
A really great place to eat with a group of friends or family. Atmosphere is lively and staff are generally friendly. Like any other Korean BBQ place, this is pricey but they have really nice cuts of meat, so treat yourself once in a while.
Tay Ho (no website): 302 University Ave W STE 100, St Paul, MN 55103
This is a childhood favorite of mine for Vietnamese cuisine, reason being that my parents use to come here a lot because we're close to the staff, but also just really solid great food.
