Upon returning to the hostel, Dave and I decided to go to a cheese and wine tasting evening (Lonely Planet told us a cafe in the town centre holds it every night), before going out to dinner some nice and expensive, away from the rest of the group.
As it turned out, however, the cheese and wine tasting no longer opened on Mondays, and after failing to find a nice looking restaurant on the square, we entered a dodgy looking cafe/restaurant that Uriel, the guide, recommended, Old Bull Tavern. The food and the service was appalling - school dinner standard at best - with more fat than meat in the cheap steaks, instant mashed potato, and the "mushroom sauce" was gravy from granules with sliced tinned mushrooms stirred through it.
After that disaster, we headed to the Irish Pub again - apparently it was 'International Night' on Mondays, plus we'd already arranged as a group to have "Mendoza Monday Madness" and everyone, including Vikki and her mates, were to meet us there at midnight.
At approaching 1am, everyone turned up - Vikki and her friends were already quite pissed, but I hardly saw them as Kerry staggered in and sat on my lap (even though we were supposed to be keeping 'us' a secret) before suddenly being very ill in the bathroom, outside the pub, and finally in the pub right in front of everyone. Then she decided it'd be best for her to go home, and refused anyone's help but mine - when I eventually got back to the hostel with her, she was easily the most drunk I'd ever seen anyone... long story.
