looking for uni (sea urchin) at an all-you-can-eat sushi joint in las vegas. Not a fan of todai but have read good things on this board about Mokino. Does Mokino have uni? Also if it is an all-you-can-eat a la carte type place, is there a limit on how many servings of uni you can order? Any suggestions as well as prices for dinner would be greatly appreciated! thanks in advance!
