Pasqual's is not a bad place to go, but it just doesn't live up to the expectations of an upscale Mexican restaurant. The margaritas get high praise, but the selection of beer was too low. Food is good, but the menu selections are redundant/not enough variety. I do like the chipotle rice, it's a nice twist on the typical "Spanish rice". For the higher-than-average pricing, the food doesn't deliver (especially when you have to pay for chips and salsa!).
Atmosphere on the deck is nice, but it can tend to be noisy inside--difficult to carry on a conversation--so I would not recommend sitting indoors.
Staff was hit or miss. Front of the house experience was a little awkward but table service was fine.
Long story short, it's worth a try if you haven't been there and you want to see what else the SW Madison 'burbs have to offer.
