Although I would love to give it another chance because I feel it could grow on you.
It's a sleepy town with not much else to do besides tour/bicycle the vineyards. I didn't see a building higher than two stories. A big change from BA.
I did a wine and olive oil tour. Also walked around alot. It is a nice city for walking and I stayed at two different hotels. Ibis Hotel when I first got there---great hotel but not near the city center and Argentino Hotel which is adjacent to the main plaza, Plaza Independencia. The plaza has a small museum, a nice fountain and tons of market stalls. I bought some fernet as a gift for a friend. For some reason, Argentinian people are obsessed with this drink. It tastes basically like Sambouca, which is iffy at the best of times.
The town is a little sleepy but I wouldn't mind going back and checking it out again. I went there in order to be able to take the bus to Santiago, Chile and avoid the $140 airport fee if I had flown into Chile. Plus I wanted to be able to say I had taken a bus across the Andes (aka the mountains where the Uruguayan soccer team crashed and had to eat the corpses to survive).
You can take a bus across these mountains very easily and very cheaply, although they weren't nearly as big as I thought they would be. In fact, I felt a little jipped. But it still was beautiful scenery and hairpin curves at points. You go through customs half-way and as is usual, you are expected to tip all the bag handlers. Travel time to Santiago is about 5 hours or so.
