I have been there too. Too loud for me too: so loud it was painful. And the waiters came to ask every single minute which snacks we wanted. I had to wait 20 minutes for my change after I paid with a 1000 B. bill. (I don't mind Thai pop music. I actually like some Thai songs.)
Yes, I went there the other day. It's rather different. It's more like hard rock. Brewhouse is more like poprock from the 80's and 90's mixed with classic (Enzo, the Italian guy, has an incredible voice). We're into 80's, 90's, poprock and even Thai poprock. It was rather disappointing for us. But I can imagine it's great for people that like the style.
Are these any other recommendable pubs or restaurants with live pop/rock music in the style hops brewhouse in Pattaya or around?
(I am more interested in the music than the food)
