I went today at lunchtime. I was the only customer. I am from the UK and a self-proclaimed chip geek.
I ordered the small cod and chips and mushy peas. I started to read a news article on my tablet and before I had finished my food arrived. This was a little suspicious for me. I still cook chips, when back in the UK, the old fashioned way as my mum always did in a tradtional deep fat fryer with a lip for holding the basket above the oil to allow the oil to reheat before a second frying. I knew the chips could not have been cooked fresh. They were too "narrow" to be real UK chip shop chips and a bit soft.
The fish batter was crisp and the cod very good. The mushy peas were OK.
Overall for 380 Bt it was OK. It's not so easy to get great fish&chips in the UK so I woudn't expect perfection but I am a firm believer in freshly cut chips cooked to order. For me, the other places I used to more regularly eat fish & chips at, provide better value for something comparable.
I would knock of half a star for not having a plate large enough for all the food.
