This is a Round Table sub-chain (small group of related stores) where one of the stores is in San Mateo (the other convenient location is in Palo Alto). This Round Table is great -- they are not often crowded and the staff is really responsive. The best attraction to this particular Round Table is the kids' play area. We always go to give the kids some time to run around (especially in the rain) while we either eat or just relax. They have a train table, legos, and other kids toys from IKEA. Definitely worth the trip.
Be forewarned -- they watch a *lot* of Fox News here.
