When in Dublin, the tourists apparently go to The Temple Bar. That isn't necessarily a good reason to be there but a French girl I met had it listed in Le Routard, and so off we went. The live music area is very cosy, and it is a nice space to have food and a drink.
I was only after something light only for myself, so the Irish Smoked Salmon & Smoked Trout platter with Guinness bread, cucumber pickle and salad €12.5 had me from the word Irish. In future I think Galway Bay oysters, black pudding platter or an open sandwich may be alternatives.
The fish was nicely smoked and not too strong, although I couldn't discern the smoked salmon and trout since they were heaped together. The bread was nice and moderately dense. The music provided entertainment and the atmosphere was sound. It may be touristy, but I thought it was worth a visit in the end.
