i was ther in April and I believe Pettels was open until about 10 or 11pm.
The drinks were good around $6 for a fruity alcohol concoction. The bartender was very friendly. I believe they had a TV there, I remember sitting at the bar for a while and looking at the TV.
There is another bar inside the food court at POP that opens at around 5pm, but we didn't get a chance to try it.
have fun!!
