Last Friday night, my husband and I went to this Japanese bar we've been meaning check out and was pleasantly surprised.
The place is called Den, and is on B Street, around the corner from the new San Mateo train station and across the street from Trag's. I don't have the exact address with me right now, but if someone needs it, I can look it up.
They serve traditional and fusion japanese food. I personally think they are stronger in the fusion area. I had this great Indo Japanese fried roll, asparagus wrapped in pork and then fried, and also this lovely pork in a ginger and soy sauce mixture. Prices go from $5 to $10. But the best news is that they are open till 12:00 and take orders for food till 11:30. With my schedule, I think I am going to be going there a lot.
