We were walking down Broadway at lunchtime trying to decide on the perfect uncrowded, sun-soaking lunchspot, when it came to us. Actually, it was printed on a sign that advertised La Puerta's lunch specials. That's when we remembered that La Puerta has an upstairs deck overlooking Broadway -- and that their food is resolutely mediocre, virtually guaranteeing light occupancy. How right we were. Just one couple was sitting outside, discussing a California "growing" operation. We had our choice of tables con umbrella and sin umbrella. We went sin. This is a strictly a health issue for us; as you know, a vitamin D deficiency will kill you dead. And sun-starved Seattleites tend to have dipsticks that read ADD MORE when it comes to D. "Some doctors" say that 10-15 minutes of non-SPF sun exposure is all it takes. We don't know, we're not a medical doctor. All we know is that a) our chimichanga was subpar, b) Chicagoans sneer at Seattle's winters, and c) we should have never told you about our secret sun spot.
