If you are looking for a local diner to support instead of the big over-hyped chains like McDonald's, then Arnold's is definitely a spot you need to try! I spotted Arnold's on the coach coming back from Pisa and am very glad we went there. The restaurant is compact, and the owners are very welcoming and friendly. Arnold's is open from 11;30 to 15:30, then there is a short closure and it re-opens at 18:00 until 02:00 in the morning. In terms of the food, it was brilliant! The burgers themselves were cooked very well, and tasted great! I would recommend the 'Happy Days' burger. Also, the food arrives within 2-5 minutes of ordering, which is exceptional. Arnold's is also very accessible, it is within walking distance of the station, but it is also conveniently on the T1 tramvia line, just a 1 minute walk from the Porta al Prato stop. Overall, the service, food and location are fantastic. Plus the food was really well-priced. We will be eating here again!!
