For Sweetie Pie's, you will take Highway 40 west (This section of 40 is still open) to Boyle. Left on Boyle, then right on Manchester. Just map it for a copy for yourself.
Like I said before, don't go late at night by yourself. Going for dinner will be fine.
Since you will be downtown, there are some yummy places on Washington Avenue, just a few blocks from where you are.
Sushi - Wasabi
Fusion - Lucas Park Grille
American - American Place
Tapas - Mosaic
Breakfast/Lunch - Rooster
Fondue - Simple Fondue
Steak - 15, Mike Shannon's
Pub - Tap Room
Of course, these are just some places to try. There are other places that are hidden away, like 10th Street Italian, that are good as well.
Enjoy your trip here!
