Seriously, naming a restaurant Philthy is akin to saying Bomb in an airport, it should never be done, but Once you get over the name and step inside you find a clean eatery with some good to great sandwiches depending on choices.
They also offer lunch combo which is a good value. I've tried a few of their sandwiches including original and big texan and I'd stick with the original with as little sauce as you can get by.
Staff are very friendly and more than happy to help with selecting a 'wich.
