I have been to both Chun locations in Allentown and Hamburg. Allentown used to be great, then went downhill as others mention. It appears the Allentown location is still open but under new management. There are some ok reviews in the Allentown section recently.
Most recently I have been to Hamburg, as I am living to the north and my family I visit most moved to that area and i stay with them. I've had only one bad experience there, I think it was Lily who it seems was in Nanticoke a while back. I was going for my Judy fix and was sad to see Lily had replaced her - this was maybe 18 to 24 months ago.
Judy was great, I saw her in Atown and Hburg, many times in Hamburg. My last visit at the beginning of the year Anna was there and she was very good. Reading the reviews, Michelle was in Hamburg with great reviews, but it was mentioned that she left for Nanticoke a few weeks ago. If she is still there, she could be worth a visit. I will be visiting in abut 6 weeks and may stop in Nanticoke, depending who is in Hamburg. I also have family in Nanticoke area as well. I will be checking reviews for both Nanticoke and Hamburg, if you have any info on Nanticoke please message me or post here.
Regarding CC and booking online - I have used this in both Allentown and Hamburg with no issues. I really wanted to see someone and for me it makes sense to be sure to get the time I want, as I always have some relative or friend I am needing to see, so my schedule is pretty hectic. The curious thing was they actually charged more for HF if you book online, possibly due to CC fees?
But there were times I had some unexpected free time and no time to book online. I called and got in right away, so their warning about only booking online is BS. I only do online as I want that 9am slot first thing and am willing to part with a few bucks to get it.
Nanticoke sounds interesting as they have exercise room and indoor garage (must request when booking) for more discreet access I would hope. I can see myself trying it out.
