We love PT, but have done both. Theming is cooler at Sci Fi, but its not a place for conversation, is a tad dark, and the food is usually not that great for hte money. On the other hand, we have had INCREDIBLE meals at PT, we split a meal each time and have food leftover, so its a good value for us. And the onion rings are great. Theming is cool, too, and we've always had great service =0
