In my mind, Spoon and Fork Plus floats towards the upper end spectrum of AYCE restaurants with a focus on nice decor, an upscaled atmosphere, and speedier service using iPads for your order.
We had a family holiday dinner here back in holidays of December and I really enjoyed the overall experience.
This particular location offers Japanese, Thai, and Italian. I think their wow factor item is the escargot that is smothered in garlic butter. At the very least, we enjoyed it by ordering at least 10-12 dishes of it over the course of the meal.
There was a lot of choice on their all-you-can-taste menu from all three cuisine styles and browsing through the iPad made it really easy with the pictures of each menu item. My only one issue is with the tempura basket offering which comes with a variety of tempura vegetables and tempura shrimp but there is no option for just tempura shrimp. :-\
The food did come flying out of the kitchen and it made for room at the table a premium so my advice is to go with small orders of dishes at a time so you can smartly pace yourself.
I did enjoy the selection of sashimi on the menu and they also had some selections that had a bit of extra flourish like seasoning/herbs.
Overall, I think the experience is worth the price of admission.
