I don't even eat sushi and I've been to Yummy Grill more times than I can count. Why? This place stays open LATE. And they serve inexpensive, paint-stripper sake. And very decent chicken teriyaki plates that come on top what is essentially a small salad, which I always appreciated. Great garlic edamame and reverse happy hour values. Hands-down my favorite place to go after hours when I don't want to leave the neighborhood or go to a sad casino-sportsbar; Yummy Grill is always full of lively (drunk) people and efficient service.
Giving a three because this place isn't exactly a cultural or culinary standout- it's just real good at what it does: be an affordable, late-night ,extremely decent place to pick up sushi and relax with friends.
