This was my first visit to this restaurant and judging by this experience it wont be the last. I was very impressed, in fact I don't think I could fault it! Everything from the decor and style to the food and service were excellent. There were 6 of us and we all agreed it was delicious and the waitresses were friendly and helpful-excellent all round!

had dinner for 4 on 11th July 2008. The location is good, the dining room and staff are excellent. HOWEVER, they really just miss the mark with the food. It was "OK" with some serious flaws. A few hints to the kitchen: Chips, when "styled" like jenga blocks should be closer to the size of tabletop jenga, not the outdoor version, they are WAY too big, unappetising and just don't work. Belly Pork should be unctuous and not gooey, flabby fat. The steaks are a little on the thin side (which makes a rare steak very hard to do well). Last negative is the WATER - when serving tap water, it really does need to be filtered, as is, it was vile. HOWEVER, all this being said, the Glass Blowing House has great potential, a few tweaks here and there with the menu and it will offer Plymouth a very pleasant experience.

Fantastic location and well set out. Poor service and poor main meal. Starter very nice. Open area where you can watch food being prepared with a chef stood behind handling food whilst wiping his nose. With the hand that he continually wiped his nose he then handled the food. (He only had the use of one arm so his unused arm was kept inside his apron where the cloth was also kept for wiping the plates!) Food left under a lamp whilst waiting for other parts of the meal to complete the dish. Shrivelled pieces of chicken served with his germs at a cost of £75 for 2 people for lunch, not very palatable. Complained to two different waitresses who both said they would inform the manager but no comment from the manager. Would not go here again nor recommend it which is a real shame as the setting is fantastic and the place very nice to sit in but the staff are lacking what you would expect for a restaurant of this calibre which is a real shame as we were so looking forward to our lunch.

Fantastic location, great food, good selection of wine and value. 3 main course and a side, a good bottle of wine and a pudding (2nd to none!) came up to £74. Service could be improved though. 3 waitress for about 35 covers (2 behind the bar)- staff/punters ratio too low for what is sold as 'classy' restaurant.

Had the grave misfortune to dine at the Glassblowing House Restaurant on Saturday night (1st May 2009). Sat down at 7 pm - ordered two glasses of champagne and got cheap Prosecco - probably because they didn't have any champers in stock or were afraid to open a bottle in case the rest didn't sell - but whatever it was just served up without explanation. The portion szes took the concept of nouvelle cuisine to extremes -I do not have a huge appetite but even I complained about the fish portion measuring two inches by three, the two very small asparagus spears, three 1cm square potatoes and four chorizo shavings. We finished eating at 8 p.m. and before my coffee cup was empty the bill was on the table and the waitress standing beside me asking how I was to pay. Absolutely disgusting and a place I shall never visit again and I will ensure that I never recommend this place to anyone! John Stevens has been in the business long enough now but clearly has not learned how to please his customers. Absolute rubbish!!
