The Peppermill - Man, it seems like this place would be terrible but I swear they have some amazing burgers and the atmosphere is very retro. It's a must stop every time we're there with my Vegas crew.
Pizza Rock - might be the best pizza in the world (after Pequod's in Chicago of course). Evil Pie and Good Pie are both good too.
Heart Attack Grill- last time we went it has REALLY gone downhill...
Gambling things:
The Circa is new and smoke free but is the LOUDEST casino in the world if that matters to you. Much younger crowd there.
Resorts World is certainly worth checking out if you gamble. I'd say that overall it's the best Poker room in Vegas these days.
I really like going to the Four Queens on Freemont for a short visit. It's classic Vegas that simply CAN'T be duplicated on a Friday night. El Cortez- SAME. Both take you back in time...
Pinball HOF. Don't trust the negative reviews. Does every machine work perfect? No, of course not. I swear though, I love just going there and watching others reactions to something they had no idea still exists. It's good for pinball and if you like pinball, you SHOULD SUPPORT IT! If you like newer Sterns, they have almost every single one... Tim is a good dude and him and his family try very hard to make sure that his guests have a positive and memorable experience. Believe me, this place only exists because Tim truly loves the silver ball.
Uber XL is the way to go if you have four people that drink. Everything is fairly close so rides split four ways are less than the cost of one drink.
