You have a great start! I have just a couple of suggestions.
I think "destination" would be a more accurate word than "distance".
One thing I would also make clear is a particular point of view. In the introduction and conclusion, I would speak directly to the reader. However, I would suggest that your main body be what you see, from your point of view, so that the reader can almost see, hear and even taste Joffrey's through your description.
The first thing that catches my attention is the beautiful arrangement of gray circle-shaped tables, making the place seem more wide.
When passing by Joffrey's coffee shop, I smell the tasty yet cheap coffee that refreshes and clears my mind.
I always see welcome smiles on the faces of the staff.
If you get a chance to come to the university, make Joffrey's your first destination, and enjoy the tasty coffee, a cookie, and the good service.
Hope this helps!
