The sign outside Kenneally's Irish Pub (2111 South Shepherd, 713-630-0486) says "cold beer and great pizza." But Kenneally's pizza is better than great -- it's legendary. The "shamrock special" ($12.55) has a definite Irish twist. The toppings include generous helpings of non-greasy cheese, mushrooms, onions, bell peppers and wafer-thin slices of corned beef. The superthin crust -- just a tad thicker than a credit card -- is nice and crispy, and best of all, it's cut into easy-to-handle squares, so you can hold your grub in one hand and your Guinness in the other.
