The Mustard Seed has received positive reviews from critics such as The Restaurant's Tom Doorley,^[2] Georgina Campbell^[2][3] and a mixed review by Pol O Conghaile of the Irish Independent.^[2] O Conghaile visited the restaurant before submitting his report for it to be published on 14 February 2009.^[2] O Conghaile was on a tour of the region surrounding south-west County Offaly, County Tipperary, County Clare and Limerick itself, overlooking more well-known tourist destinations such as the Cliffs of Moher and Bunratty Castle in his attempts to locate what he described as "Shannon's hidden gems".^[2] He described his experience at the restaurant as mainly positive; indeed he described the dining area as "moody" and the service as "chirpy".^[2] O Conghaile's problems were with the food; although Kenmare cold-smoked salmon starter was "delicious" and the best of its type that he had ever dined upon, his main course of duck was "fatty enough to require a knife change" and the bacon breakfast he had the following day was "rock-hard".^[2]
