My favorite grocery store. Literally everything you could want. Huge organic produce selection and meats/seafood. Also, has its own bakery.
The sushi here won't give you diarrhea like some of the grocery stores with sushi kiosks in town. Choose some Little Soya when you can - great gluten-free soy sauce!
The Chicken Salad is delicious! Prices are good if you have a long stay at the convention center. 28,000 sq. ft. specialty grocery store with everything you can imagine!
The pre-made frozen stuff here is really great. Not that it's any better or worse for you than stuff from other grocery stores.
