My grandma, wife, and I went based on the reviews on tripadvisor. We had a great time chatting with the woman working there. However, the wine was lacking. My wife and I had the sample of 4 for $5 while my grandma had the wine-a-rita for $5. These are definitely the best values for wine that is so-so. We also ordered the Texas Cheese Plate for 2 for $14. One of the cheeses was great (Van Sorman), the other two were average for the price.
I'd still recommend the place, especially in spring and fall, but don't be surprised if you're not blown away.
