So if we apply Xandria's criteria:
Affordability - The problem is that everything is delicious, so a tendency to overorder can jack up to the final total. However, everything is so good, that you won't mind.
Wine list - All Spanish, many regions are represented here and the QPR that comes from having someone find, source and serve items that you can look for later on your own is stellar. I look forward to trying something new there soon.
Wait staff- Very attentive and knowledgeable. Excellent customer service is a hall mark here.
Food- Amazing! Catalan native Olivella brings many classic Spanish items from "Rioja to Jumilla" to the East Bay.
In summary, come for the food, stay for the wine. You will so not be sorry you did!
