Yummy breakfasts, sandwiches, lunch specials...Mutual Street Deli has all the makings of a great diner. It's got a variety of tables from booths to large group tables, it's reasonably priced for lunch with some downright cheap breakfast options, and they have servers who are adept at checking in on you and knowing what you might need in the first place. The only thing that could make it better was if the service were a tad faster. Although I've only been there during busy lunch hours, so maybe I'm just being picky.
Those who know the area will know that it isn't exactly the nicest area of town, but while the diner has been around forever, it's been renovated inside so it's a pretty decent place and doesn't reflect the surroundings at all. Be prepared to pay for street parking or for one of the many surface lots around the area, if you're not already in the neighbourhood.
