We go to Trader's Sam's Terrace, outdoor. I don't really like sitting on low couches in the dark, with all the noises. The first time was unique. Also I don't really care for many of the drinks at Trader's Sam's. They seem to ruin them by throwing in strange liquors or spices. We just order our usual cocktail at a much lower price, but still higher than at other Disney bars.
We sometimes will get a drink at the Poly in the Tambu Lounge. It gets really crowded though because of guests waiting to be seated at 'Ohanas. There is a sushi bar that serves drinks next to Kona Cafe, we will get an appetizer and drink there.
At GF, Narcoosees has an interesting bar, it is sunken from the dining room. But we have only died there. But I would rather pick up a drink at the pool bar and go and sit outside Gasparillas Grill and watch the marina and the fireworks at MK. There is a lounge off of the 2nd balcony area near where the band plays at night.
For the CR, we usually go to TOWL. But my favorite is still sitting on my balcony enjoying the view with a glass of wine.
