Ward's is a very nice, little pub on Post Road near the East Greenwich line. They have a good selection of beer on tap, featuring a fairly common cast of Irish standards.
The food is generally quite good, although I think it's a bit on the pricey side for pub grub. The service is unusally pleasant and very welcoming. In fact, the whole pub has a very warm quality to it that makes you feel right at home.
One thing that always impresses me is the cleanliness. They do a great job of making sure that everything is very clean and nice.
Overall, it's a good place to stop in and have a few beers, maybe watch a few innings on the tv's that are discreetly located at the bar, and have a good plate of fish and chips.
