No need to agonize over the dessert choices at Vincent's [2701 West Dallas, (713)528-4313]. The banana split pie ($5.50) has been a favorite at the restaurant for 14 years, and for good reason. Served in squares, it looks more like a cake, but the graham cracker crust reveals its humble pie beginnings. Fresh strawberries, bananas and pineapple are layered on top of the base, and the confection is topped with copious amounts of whipped cream and bits of banana. For a buck more, you can add a common touch of vanilla-bean ice cream to this upscale soda-foundation variation. Either way, don't split without trying the treat.
