I tried Toby's Public House on 21st and 6th recently and thought it was great. There is a good selection of beer on tap including a cheap beer that is $3 and not bad at all. The decor is well done bar decor (dark wood bar and stools and several tables). The big difference between Toby's and your typical higher quality watering hole is the brick pizza oven prominently on display at the back of the restaurant. The pizza oven conveniently doubles as a fireplace in this slightly chilly time of year. Best of all, what comes out of it is really good. The pizzas are small in size (enough for one person) but very tasty. They remind me of pizzas in Italy, thin crust with high quality mozzarella and a sauce that is very tomatoey (i.e. light on the aromatics and herbs). For those who care, the pizzamaker seems like he is from Italy.
I think the pizzas compare favorably with Anthony's which seems to be the chowhound consensus winner for best pizza in the South Slope and I think the mozzarella that Toby's uses is of a higher quality. Toby's also has 3 flat screen TVs and they show soccer on Saturdays. They also show Yankees games most gamenights. The service is friendly and the bartender will even let you taste the beers if you can't decide which one you want. An excellent addition to the neighborhood.
Leaving food aside, my wife and were remarking that they seem to have the right mix of decor and atmosphere and share this with other recent additions such as Sidecar, Beer Table and Quarter and separate this group from the likes of Pyramide which unfortunately doesn't seem to have had the right mix, even back when the food was getting good reviews.
