Masu

I've only been to Masu for their all-you-can-eat weekday lunch. For about 12 dollars, you can gorge yourself on rolls at this small sushi restaurant. Since they opened a year and a half ago, I haven't been able to make a trip down to San Mateo's downtown without stopping in and wolfing down a few rolls.

How it works: They bring you a menu, and you give them an order of two rolls to start, and they'll come back when you finish them and ask for another roll.

For non-sushi eaters there is also a selection of foods that they can get instead of rolls, such as udon, tempura and chicken teriyaki.

Note: Friday at lunch is typically their busiest day -- be prepared for at least a 30 minute wait. The Lion King Roll is not be missed (crab, asparagus, shrimp and avocado drizzled with wasabi sauce). Non-alcoholic drinks are included in the all-you-can-eat price.
