I've been here a couple of times and have only had burgers, so I can't speak for the sushi side, but I do like the burgers. I've had the Dynomite and the Kafeteria. Both are tasty flavor explosions and both are likely to become soggy quickly. I think it's probably safe to assume that all of the burgers are likely to quickly sog, which is OK if you're eating quickly! Part of this is because of the sauces and dripping toppings, but another reason is the juiciness of the burger meat.
The beer selection is OK and the bar service is OK. Nothing too crazy.
Overall, I like the place and I'll be back for burgers and maybe some sushi one day.
Tip: Be prepared to get messy if you're eating a burger. Bring moist towelettes, roll up your sleeves, don't expect your lipstick to stay in place.
