I usually come here for the clothing (to shop till I drop) but this particular visit was to specifically visit the Eve café, located on the second floor of Simon's.
It's actually a very quaint and modern café, situated in the back left corner from the position you face when coming up the escalators. They have sofas and round tables, as well as a patio area with some umbrellas and comfy chairs.
The café itself offers a variety of different foods. My friend got their grilled cheese, which typically comes with bacon inside and pickle on the side. Since he's vegetarian, he asked for it without the bacon and they kindly accommodated his request.
We also got drinks - I ordered their iced macchiato, and while one of my friends got the same drink, the other got their iced coffee. He found the iced coffee to be slightly on the sweet side. My iced macchiato, however, was perfect. It was silky smooth, but still had a very rich espresso flavour. Not bad at all!
Definitely an option to consider for coffee when in Square One :)
