It's lunchtime, you're in CenPho, and you need a slice. Stat. There is no shortage of choices, but if you ask us, there really is only one choice: this bustling little bistro at First Ave and Thomas, brought to you by one Pino Martnino, an Italian émigré who came to the Valley several years ago. Martnino features a nice array of signature pizzas — and they are excellent — but what brings us back again and again is the build-your-own slice option. At about $2.50 a slice, you can top your piece of pie with just about anything you'd like: tomatoes, basil, fragrant garlic, onions, peppers, pepperoni, and the list goes on. The crust is doughy, chewy, and crispy on the outside, the red sauce is tangy and a little sweet, and the toppings are high-quality and fresh. One slice is big enough to feed us for lunch, but who are we kidding? We can never stop at just one of these hot-out-of-the-oven gems.
