We're going to San Sebastian in 2 weeks (the 17th-19th). The 4 of us are a bunch of foodies. We like getting good value for our money but feel compelled to splurge on a REALLY nice Michelin star meal. We would like to get a meal that is unique and one that we cannot get anywhere else. We were considering Arzak, Akelare, Mugaritz, and Restaurante Martín Berasategui but if all the cuisine is on a similar level, we'll go with one with the cheapest tasting menu. I have narrowed it down to Akelare and Mugartiz from what I have read but would love all your input. Also, should we go for lunch instead of dinner? Would lunch be cheaper? Wine isnt as big of a deal for us so a more affordable wine list isnt as important to us. Thanks in advance for your feedback!
