Jumbo is a buffet places which offers Chinese food, Japanese sushi and raw fish, American oyster, Mongolia BBQ, sea food and lots of other dishes. It is very very inexpensive. There are 3 restaurant in the metro area. I have been to 2 of them. Richardson's one is the cheapest. You can basically pay $6.00 plus tip and tax for a lunch tax with tons of dishes. Excellent value. Their restaurant is big too so you can entertain a party there. My only complaint is that I always overeat in this restaurant, which is not good for me.
