This is the second time in two years that I’ve had a brilliant experience putting on a birthday drinks for dozens of guests. I cannot highly recommend Lucy Wong more. I will be doing more events here. The drink, the food, the service, the ambience is perfect for a crowd who wants a more chilled but classy time.
Good service and attractive venue which turned out nicely in photos; also appreciated that there was no minimum spend.
Amazing Venue, staff were so friendly and accommodating, the space was clean and beautiful, kept getting compliments from guests on the venue all evening. Amazing value for money, would highly recommend.
Had such a lovely evening and Thea was just wonderful! Definitely recommend booking this place for your next celebration!
The 1st floor at the Elgin was such a great little space for any party. The staff was extremely helpful, well organised and catered for all the needs of my 50th birthday. Great venue!
Everything was perfect! The place, the staff, the FOOD!!! We’ve received positive comments from the guests as well, and some of them are also planning to hold their party at Waterway. The staff were polite and very accommodating, too.
Elizabeth couldn't have been more helpful and obliging. The barge is a fun venue for a small gathering/party. We had the people walked no past singing along and dancing to our tunes! We had a buffet and some party tunes/lights etc, copious amounts of bubbly and a good time was had by all.
Excellent venue for its originality. Perfect for parties for up to 15 people. The owner was very helpful and trustworthy. The boat had to moor at a particular time and place and the expectations were met.
