I've been having a taste for fish and chips for a week or so now. I seen the words "Irish Pub" under the name of the restaurant and figured they should serve fish and chips. Walked in the staff was great, everyone was very friendly. This was a Thursday night so not so busy, but you could tell the few locals were there at the bar. Ordered my fish and chips, my husband had the recommended Ruben on Rye with Sauerkraut and we have to say the food was excellent! Service was quick, I received my food before I finished my dinner salad, the food was hot, and fresh. The prices are fair and the portions are more than enough. If I'm ever in Gilbert again and craving some Irish pub specialities, R.T. O'Sullivan's will be my first choice!
